There are about 360 known species of hummingbirds, which makes them the second-greatest number of species of any bird family, after the tyrant flycatchers. Currently, as many as 135 species of hummingbirds occur and partition resources in some localities in the Andes. The process of speciation might have been speeded up by the geological transformation of the Andean Mountains.Īs new species emerged, mutualistic plant-hummingbird relationships were forged, resulting in species with bills of lengths and shape specific to a particular group of flowers. The current geographic distribution and diversity of hummingbirds suggest that they split into many species in the Andean Mountains of South America. Keeping the Balance Between Activity and Food.Some species of Andean hummingbirds have co-evolved with the length and shapes of flowers resulting in bizarre bill shapes and lengths.They chase away much larger birds such as mockingbirds, blue jays, and even hawks. While it is uncertain whether they used their bill, hummingbirds are very aggressive to other birds in the air.However, they have a poor sense of smell. Hummingbirds have excellent eyesight and can differentiate the sugar concentration in nectar.Hummingbirds can live up to 12 years based on banded and recaptured birds.The tiny hummingbirds beat their wings at an approximate rate of 80 times per second, whereas the Giant Hummingbird of the Andes does so at a rate of 12 beats per second. Hummingbirds’ wing beats vary in size.After the chick hatch, she raises them alone. After mating with a male, she finds a location for the nest, builds it, lays eggs, and incubates them by herself. All hummingbird females are single mothers.Well-developed pectoral muscles allow them some of the most acrobatic flight in the avian world. Hummingbirds are the smallest birds (about 3 grams of the smallest species), have the lowest number of feathers (about 1400) but have the largest pectoral (flight) muscles proportionally.The Olivaceous Thornbill of the high Andes walks from a flower to a nearby flower to save energy. Hummingbirds have tiny legs and feet that they use to perch and scratch themselves.They have iridescent or structural colors that vary depending on the arrangement of the feathers and the angle of light. Contrary to what some people believe, a hummingbird cannot switch its colors on and off.They reach their highest diversity in the humid montane forest of the northern Andes, where up to 130 species occur in regions of the Andes. Hummingbirds are found only in the Americas.They occur in coastal deserts, rainforests, and alpine grasslands. Hummingbirds occupy just about every habitat. They feed mostly on nectar from flowers and small soft insects. There are 37 species of hummingbirds in the list of threatened and endangered birds. The major threat to hummingbirds is habitat loss. They are closely related to the swifts of the family Apodidae. All hummingbirds belong to the family Trochilidae.

MTBFs – A (6000 hrs), B(4500), C(10500), D(3200) What is R for the series system ? (Ans ) What is MTBF for the series system ? Total lambda is 1/ / / /3200.

Two simple structures : series and parallel. How to analyze the reliability of the ‘whole’ based on structure and component reliabilities.

Failure distributions consider many modes of failure – therefore are often difficult to characterize SE-Week 9Ģ4 Useful fact… If a system has a constant failure rate, the reliability of that item at its mean life is 37%. Systems engineers must consider all failure modes and types. Wasson suggest MIL-HBDK-470A – failure of ‘mission critical’ items. Failures may be classified as primary, secondary, etc. Mean Time Between Failures Mean Time To Failure Mean Time To Repair Since MTTR is small, MTBF approx = MTTF SE-Week 9Ī ‘failure’ is any event where system is not functioning properly. l = 1/q = 1/MTBF SE-Week 9Ģ1 Wasson MTTF Light bulb failures SE-Week 9Ģ2 Wasson MTBF Wasson suggests MTBF = MTTF + MTTR L is “instantaneous failure rate” M or q are MTBF. SE-Week 9Ģ0 Failure rate and MTBF R(t) = l = 1/q = 1/MTBF This is the accumulated value, what you get doing the integration. Mean life (q) is average lifetime of all items considered. R(t) = 1 – F(t) = If ‘time to failure’ is (assumed to be) defined by Exponential Function (Constant Failure Rate) then – f(t) = Like, if half fail in year 1, then half of the remaining ones will fail in year 2, etc. Integral from t to infinity is “the rest of the probability” beyond t, i.e., the probability it didn’t fail up to time t. Like, what are the odds of the system staying “up” for a year? At t = 0, R(t) = At t = ∞, F(t) = 1.0. R(t) = 1 – F(t) F(t) is the failure distribution or ‘unreliability’ function.

I would recommend this for anyone needing a fairly light weight, easy to use hand mixer. Made a pound cake and that blended smooth and lite. It makes a fast task with angel food cakes, whips the egg whites up nicely. Very easy to clean without the middle stem and your batter won't stick in-between the wire and have to dig it out like old-fashioned beaters. Make sure you hear each beater click into place before turning on the mixer or you will lose them by flying out of the mixer. Make sure you put the beaters in the correct holes.the larger hole takes the beater with the extra metal ring where it clicks in the hole. Then I turn it on low and quickly stir around the bowl and it mixes up pretty fast. I have found if I just stir a little with the mixer (off) then it helps to start the mixing procedure. The low speed is pretty high if you want to mix dry, powdery flour with liquids - expect dust flying. Review:For a 3 speed, low cost mixer, this is great. For all your other mixing needs, I recommend this one highly-I'm very pleased with it.Date:Reviewed in the United States on November 1, 2012 For that I'll stick with my immersion blender. That might be one drawback-this mixer is so powerful that I can easily see it slinging whipped cream all over the kitchen. It also comes with a wire whisk for whipping cream, although I haven't tried that yet. The Cuisinart comes with a set of wire beaters that are substantial enough to handle any cookie dough, and they don't have the center post going all the way through the beaters so your dough doesn't end up getting all hung up in your beaters. Read customer reviews and ratings about Cuisinart CHM-3 PowerSelect 3-Speed Electronic Hand Mixer at Overstock. Great for right or left-handed bakers, and helpful when you've got a plug on one side or the other in the kitchen. This mixer is small and light and easy to handle, and it's got this really neat swivel cord so you can push the cord out of the way and it doesn't drag in your cake batter. I don't think there's much that a sugar cookie won't cure. The new Cuisinart is extremely powerful-as a matter of fact I haven't had the nerve to rev it up over a 3! I do all my own baking, and take cookies to the office as a way to lighten up the mood of the office these days. I had been using my old reliable Black & Decker hand mixer (very very old) that I had bought myself 25 years ago. I received a new Cuisinart PowerSelect 5 speed Electronic hand mixer as a Christmas gift. The best solution I've found is to use a very large bowl (8 qts) which is deep enough and wide enough to contain any wayward ingredients. It starts off too fast, which is somewhat of a problem when trying to beat something light or powdery (cake/pudding mixes, creaming sugar into butter, etc). The only issue I really have with this mixer is that the low speed isn't really very low or slow. I do like that this mixer is strong enough to handle even the stickiest of doughs (which my old Hamilton Beach mixer never could handle) without getting bogged down. The beater attachments are also fairly long, so the batter would have to work itself up ridiculously high for it to come anywhere near the motor anyway. not a good thing, because it's not exactly easy to clean out! The Cuisinart HM-50 5 speed mixer solves this problem by getting rid of that center post there's nowhere for the dough/batter to get caught up. The problem with most mixers I've used is that the center posts on the beaters sometimes get clogged up with dough/batter, and if you're not careful, it works its way up into the vents for the motor. Even though I have a stand mixer, there are just some times that you need a good hand mixer. In May 2008, the Fedora 9 and Ubuntu 8.04 ĭistributions included IcedTea 6, based completely on free and open source code. IcedTea provided free software alternatives for the few remaining proprietary sections in the OpenJDK project. One of the first benefits of this agreement is tighter alignment with the IcedTea project, which brings together Fedora, the Linux distribution, and JBoss, the application server, technologies in a Linux environment. On November 5, 2007, Red Hat signed both the Sun Contributor Agreement and the OpenJDK Community TCK License. It began life as an OpenJDK/ GNU Classpath hybrid that could be used to bootstrap OpenJDK, replacing the encumbrances with code from GNU Classpath. To achieve openness, Red Hat started the IcedTea project in June 2007. Due to the encumbered components in the class library and implicit assumptions within the build system that the JDK being used to build OpenJDK was a Sun JDK, this was not possible. In order to bundle OpenJDK in Fedora and other free Linux distributions, OpenJDK needed to be buildable using only free software components. IcedTea and inclusion in software distributions (moved to IBM Semeru Runtime Certified Edition at version 11) (moved to Eclipse Temurin at Adoptium in 2021) Linux distributions have always offered their own builds, and Windows also offers one now ( November 2020)ĭue to Oracle no longer releasing updates for long-term support (LTS) releases under a permissive license, others have begun offering builds. Further details may exist on the talk page. Please expand the section to include this information. This section is missing information about presence of installer providing system integration (Windows registry, Mac framework, Linux MIME). Unlike past JDK Release Projects, which produced just one feature release and then terminated, this long-running project will produce all future JDK feature releases and will ship a feature release every six months according to a strict, time-based model. Since JDK 10, the effort to produce an open-source reference implementation of the Java SE Platform was moved over to the JDK Project. OpenJDK was initially based only on the JDK 7 version of the Java platform. The experimental -XX:+EnableJVMCIProduct flag enables the use of Graal JIT (JEP 317). OpenJDK 9+ supports AOT compilation ( jaotc) using GraalVM (JEP 295). The only currently available free plugin and Web Start implementations as of 2016 are those provided by IcedTea. Sun previously indicated that they would try to open-source these components, but neither Sun nor Oracle have done so. The web-browser plugin and Web Start, which form part of Oracle Java, are not included in OpenJDK. The OpenJDK project produces a number of components: most importantly the virtual machine ( HotSpot), the Java Class Library and the Java compiler ( javac). OpenJDK is the official reference implementation of Java SE since version 7. Were it not for the GPL linking exception, components that linked to the Java Class Library would be subject to the terms of the GPL license. The implementation is licensed under the GPL-2.0-only with a linking exception. It is the result of an effort Sun Microsystems began in 2006. OpenJDK ( Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).

I have three media player / DMA devices in my house: I'm hoping somebody can help me fix or workaround a very frustrating problem.Hope this is helpful for someone to help with my Serviio issue. Until recently, I used TVersity as DLNA server for all three. My desktop PC died, so I've now switched to using a Synology DS1812+ NAS as DLNA server. I have quite a large collection of WMV files which don't use square pixels. The PS3 plays these files at the correct aspect ratio (as does Windows Media Player), but my other two devices don't - the picture looks horizontally squashed (so widescreen programmes play in the area that a 4:3 programme would occupy on the screen, with black bars either side - people look very thin!). I can 'cheat' on the ACRyan by manually setting the options to say it's connected to a 4:3 TV, which it isn't. That has the effect of filling the screen with the picture, although it's a pain to have to keep switching the setup options in between playing these files and other types of files. The Bravia TV simply refuses to play them at the correct aspect ratio - whether playing the file via DLNA over the LAN, or locally from a USB flash key. And because the media player is integrated into the TV itself, I can't use the "4:3 TV connected" trick to workaround the problem. The pixel dimensions of a typical sample file exhibiting this problem are 672 x 544 (so SAR is 1.235). Using the WMV-aspect-ratio-changer tool by crypto (WMVARChanger.exe), I can see that the PAR is already set to 1.44 (16:11). Implying a DAR of 1.78 (16:9), which is presumably why my laptop and the PS3 play them just fine. My Synology NAS's DLNA server has the ability to set "custom MIME types" and you can manually override the auto-selected device profile to select another one (the auto-selected one is called "Sony BRAVIA"). but at this point I'm at the very limits of my DLNA expertise - I don't know which MIME type string and/or profile might help me to fix this (if any). Is there any way to get the TV (and hopefully the ACRyan) to respect the aspect ratio flags in the ASF header of these WMVs? And, regardless, the Bravia telly has the same problem playing the files from a USB flash device, so it's not really the DLNA server's fault. Thanks in advance for any help you can provide! I really don't want to have to re-encode everything if I can possibly avoid it, but at this point I'm struggling to think of another solution. I was using the "Media Server" (official Synology) DLNA server package on my NAS before. But I've just got Serviio 1.1 working on it in the past couple of days. It seems that Serviio has far more granular control over different players/renderers than Media Server does. Serviio uses a 'profiles.xml' config file to define different profiles for different devices, which are either auto-selected (e.g. Each profile defines how to present different types of files to the player.Ī real bonus is that Serviio can be configured to perform real-time remuxing/rewrapping or even transcoding of files, effectively enabling players to play stuff they usually reject or get wrong.īy HTTP header parsing or uPnP device name) or can be selected manually via Serviio Console. |
